actually, i think what i want for the isos is this company called shopify that is located in canada.  they have a 5 gb upload limit, which is enough for a dvd. it would be nice if that could come up to 25 so i could host blu-rays, but that's a distant concern.

that should help me avoid tax problems because i'm not jumping borders.

i've never used this site before and i don't know much about it, but it's apparently kind of big.

i would expect something to come up there in the next few days.
