In a new interview with MMO Sanctuary, executive producer Dan Stahl answers many general questions about the Foundry toolset.  While many of these answers are not new, he did share a tentative date for the Foundry to go live on Holodeck:

We are going into our final round of Beta testing with our v.1 update. This update contains many features requested by our Beta Testers. Once that update has had a chance to go through trials on the TRIBBLE test server, we plan to open the Beta up on our live HOLODECK server and make the tools available for anyone to use. Our tentative date for the Foundry being on HOLODECK is sometime in March.
