Looking at what Kenzer is doing with their kalamar setting, I really can't see the downside, if one is careful, with skirting the GSL altogether. Using Kenzer as an example, 3pps could support 4e while at the same time keeping ultimate control of their IP if and when WoTC decides to change the parameters of the GSL.
The announcement of Kenzer supporting 4e is IMO a great thing for folks, like myself, who are developing our own IPs and wouldn't be averse to supporting 4e so long as we can create materials using the same IP for other OGL systems. I would never knowingly sign onto the GSL, as it currently stands, with a flagship product that would need to be mothballed at WoTC's sayso should WoTC choose to revoke the GSL for whatever reason.
