I can answer most of your questions, although I'm not a MythFrontEnd  
developer. JSYK, I've been running the front end on a PBG4 1.25Ghz w/  
512MB, but I don't use HD video. (comments inline)

Yeah, pretty much.

There is the possibility of the hardware decoding being offered by  
the video interface (DVD Player uses it), but afaik, more than one  
developer has been having problems accessing that functionality -  
Apple hasn't published the APIs. I wouldn't rely on it happening soon.

Not to be rude, but my vote goes to pipedream, sorry!
