Assembla indeed offers hosted Perforce, (and hosted Git, and hosted Subversion, and even all three in the same workspace) but only as part of their collaboration suite. To get your money's worth, you'd also have to buy into their wiki and ticketing system (which does integrate into whatever repository you choose) and planning tools. Which aren't bad, but may not be what you're looking for.
