While I don't know of a generic multi-pitch stripboard equivalent for SMD components, the Schmartboard|ez system and their Schmart Modules, give pretty solid productivity for prototyping, much like stripboard did in the DIP era.

The solder grooves and raised solder resist make it easy to hand-solder small-pitch SMD components, both basic parts like passives, and high pin count ICs. The time saved in DIY prototyping projects is very significant, as well.
The original Schmartboard products were oriented towards soldering an individual SMD IC onto an adapter board, which would then be soldered onto traditional 0.1" pitch layouts. The new module products provide for entire susbsystems, i.e. one or more SMD ICs and their associated support components, onto a suitable module, and interconnection of such modules with Schmartboard|ez boards.
Thus, for instance, an SMD RS232 subsystem in its entirety can be prototyped onto a single suitable module board:
The product listing and identification on the Schmartboard site could be a bit confusing, the site could do with some usability reviews and redesign, but the products are excellent.
I have tried similar looking nameless SMD proto boards bought on eBay, but they aren't quite as effective. The Schmartboard grooves, specifically, make a world of difference.
