Honestly, I'd think it's about time to change the recommended MPEG-2 encoder to HCenc. But that's just me.
I've not had to rip any Blu-rays yet (nor do I even have a BD-ROM drive, or any Blu-rays to start with), but I know there is work on open-source libraries to handle it, for example so mplayer supports playback like it does with libdvdcss. Once that comes to fruition it'll be possible.

It's already possible. DVDFabHD does it. Possible isn't Free (or free for that matter).
As for after ripping, I've just been using dss2() to pop it into AVIsynth. It's all the same from there. Only other stuff that needs to go into the guides are resize numbers for 720 and 1080 (the former because a good deal of people's systems can't handle the latter). Maybe a note about how pre-processing takes a bit longer with the increase in frame size (6x larger for full 1080).
The ripping is the only issue - and only really an ethical one at that. Suggesting to so many people that you should use a non-free tool results in alarming rates of piracy of that tool.

There are a number of reasons that I haven't done so already:
1. A few years back I tried making some mpeg2 encodes for awa using quenc and hcenc, and awa kept telling me that me encodes were screwed up. I never figured out what the heck I was doing wrong, so I decided to just play it safe and stick with tmpegenc.
2. mpeg-2 is mostly useless for amvs except for sending to conventions. And for that, the bitrate is generally high enough that you wont see serious artifacts when its shown at the convention.
3. Hcenc only encodes the video stream, meaning users will have to encode audio seperately, and then mux them with something. This complicates things a fair bit. I also don't know a good muxer that is both easy to use and works well.
4. I keep hoping the conventions will all upgrade to mpeg4, and then this will all be moot.

I was referring to a solution that doesn't contribute to software piracy. I know DVDFabHD can do it.
As for the actual opening it part, I'd go for DGAVCIndex or FFmpegSource2 (although if you don't remux to MKV first, you need Haali's splitter installed so it can handle TS). Apparently there actually are some situations where DSS2 is not frame-accurate.

As to the non-frame accuracy, is that for playback? Because I'm just using it to load, filter, and dump the entire disc as a single file anyways. I'd never recommend editing with the scripts themselves with HDDs so cheap nowadays. It's silly.

I do recall that the version of libavcodec it depended on had some caveats, but there seems to be enough buzz around the -NV versions.
It may be for playback, or it may be in general. The underlying point was that it relies on PTS timestamps, and if the PTS is wrong or absent, DSS2 ceases to be frame-accurate. For a quick pass-through it may be okay, but I'm not sure how it would react with filtering that manipulates frames like IVTC or other analysis routines do.

Blu-ray can only store interlaced video at 30fps. Hence, anything that's supposed to be 30fps can only be stored as interlaced. For 720 this is less of a concern because 720p60 is supported, but 1080 is restricted to just 1080p24 or 1080i30 (or 1080i60, if you go with the way the spec says it - still the same thing because they're talking fields, not frames).
Whether you see it in the wild is another matter, but the possibility exists (and what are the chances that the weirdness that occurs with DVD hybridism is rendered impotent on Blu-ray?).
