Storage clips in Lagarith YV12 ?

I usualy store my clips in Lagarith with RGB colour space (as it is as default setting). I work with someone together on an intro for an amv contest and I have to send him my parts. Anyway I´m not a fan of sending huge files over the net .-. So I was wondering if I could just send him a Lagarith in YV12?
Yeah of course I can, but I want to hear first if there could be problems with it. If I remeber right the guides say that I shouldn´t change too often the colour space, because it can mess something up. Well I guess it will be ok to make the whole project in looseless YV12 before we´re converting it to XviD or x264. Mhmm... If I remeber right again, DVD footage is already YV12 and x264 works in YV12 too...
I could save up too 2 thirds of the filesize if I use YV12 in my Lagarith file and that´s really alot.

Could you tell me some problems that might come up and how I avoid them?

Colorspace conversions can produce slight degrading of the quality. Generally, I would recommend to only store the lossless master file as YV12-mode Lagarith unless the video editor supports YV12.

Note: Lagarith's RGB (Default) setting actually preserves whatever the input colorspace is. If you give it RGB, you'll get back RGB. If you give it YV12, you get YV12.

It would be ideal to keep everything in YV12 all the time. The problem is that editing programs work in RGB. So if hes going to take it into an editing program, then thats another conversion. Honestly though, a couple colorspace conversions probably wont have much, if any visible effect.

Thank you very much guys. That will spare me a lot of MB.
