Ideas for a PC based lichen database system.

As a former contract programmer, it occurred to me that a computer program could be written that would have numerous advantages over the usual dichotomous key. I have looked at a few of the items that are available on line such as the very nice offering at "http://nhc.asu.edu/lichens/Navikey/navikey.jsp". But these lack all kinds of functionality that I wish they had. As such, I am working on creating a program that will not only help me identify what I collect, but manage my collection, be a repository for my field notes (searchable by sample, date, location, etc.) Is there anyone else that would like to discuss or collaborate on such a project?
