Using google to find software, even webware, for 4E produces few useful results. Most of the hits for the searches I did were for reviews for 4E itself or for the upcoming D&D Insider. This worries me somewhat, because it seems like there used to be dozens of software projects on the net for 3rd edition at any given time. Sure, many of them failed - but out of these projects came some very usefull and long lived icons of the community. To name a few: PCGen, Jamis Buck's Generators, Crystal Ball, and many more (too many to list). I even got into the fray myself, and developed an NPC Equipment Generator (first in Perl/TK, then later in Java).
But now, 4E has been out for almost 2months and I am not hearing or reading anything about new, groundbreaking software tools for the game. It seems like everyone has taken the same old bait from Wizards of the Coast again, and is waiting for D&D Insider (which is likely to be vaporware) to be released. Even if it does get released, do we really think it will have all the functionality and flexibility of a mature product like PCGen? I'm no doubt playing the skeptic here, but I'm just surprised that there hasn't been a noteworthy effort by the players community to develop a set of online tools to make playing easier on the table-top. Fer fucks sake: even a Tablesmith style encounter generator would be good.
[POST PUBLISH EDIT] : I did find Asmor.com to have some decent tools for 4E DM'ing. But, other than that it seems pretty sparse.
