After briefly researching the OSL, I should add that it does not meet an 
additional criteria which hadn't yet managed to articulate: I would like 
the license to minimize incompatibilities with the GPL.

I am aware that the AGPL is *not* compatible with GPL V2, but I believe 
that getting an exemption from the copyright holder of GPL code WRT the 
AGPL will generally be easier than doing so for an OSL work.

Also, the AGPL is at least intended to be upwardly compatible with GPL 
V3 (whether it ends up being so in practice remains to be seen, of course).

Over the long term, an AGPL-like approach seems to minimize (though of 
course not eliminate) my licensing headaches for combining my work with 
GPL code.
