[BioC] Conservation tracks in BioC?

[Paul Leo]

Would like to get some advice on the best way to access Conservation
data from UCSC like the human-17 way conservation etc. Now I know HOW to
get it... ftp, table browser, SQL from UCSC.....and  I was going to
download it and put it into an Rle object for later use. I need the lot,
not small pieces at a time..

My question is is it already packaged up in R-Annotation somewhere and
I've missed it?

Thanks
Paul
