There is a bit of a ghetto/unreliable way to find the most recent version in a reasonable amount of time. Not perfect, but seems like it would have worked for the past year and a half, and reasonable to think it might continue to work in the future.
If you look at
http://www.project1999.com/forums/forumdisplay.php?f=11, all the threads with patch downloads in them have the standard spiel ("The latest patch contains new required files. Download and extract the Project 1999 Files (V##) to your EQ Titanium Directory.") in their tooltip. A single simple http request will net you those tooltips, and a regex for "V\d+" or somesuch over the entire http response should get you the most recent version number along with a few recent but outdated ones. Should take less than a second. Don't need to be logged in to the forums or anything, either. And once you have the highest version, you can work backwards from that to the patch file url.
Relies on several assumptions being true, like the most recent patch being on the first page of that subforum (pretty likely), the post with the most recent patch having that standard spiel in its first line so it ends up in the tooltip (again, seems consistent over the past year and a half as far as I can tell), etc... but there you go.
Not ideal obviously, but something you could jump on right now rather than waiting for an official response and action that may never come.
