LM-Hashes can be submitted to www.plain-text.info they also have an IRC bot that can crack LM very fast. The site is an online distributed Rainbow crack data base.

Yea myself and a few other security guys decided to try an automated rainbowcracking server. Back in 2003 and we where the first to get an online Rainbowtable cracking service up and working and it was and might still be the largest set of tables on the net but most of the tables are still privet do to the harm they could cause if completely open to the public... it just keep going from there and we got a lot of tables (many tyrabytes). To keep the riffraff down we limited anonymous submissions to like a few per hour for the whole internet. But our IRC bots can crack many hashes in almost real time (LM, NTLM, MD5). The cool part is you can search for an already cracked hash to see if the hashed you have now have already been cracked. One of the ideas behind it was to assist Pen testing of password security and to see if it could be done.

Well I am just one of 7 admins of the site. Me and one other started it and merged with another group to make it what it is today. I can not take too much credit for the site or the mission as my work has keep me to busy to do too much with the original team but I am still an admin. I would say if you want to know more and maybe get involved go to the site read the FAQ and then go to the IRC room and chat with the team. They are always looking for more tables and clients to help run the distributed cluster. If you join up you get limited access to the online tables and can submit hashes for your pen-testing needs.

FYI not everyone will be accepted and it's kind of a small trusted team so if you really interested in getting into it take your time to meet the team and build there trust.
