I am looking for a distribution method for all kinds of files that are licensed to be freely distributed. It consist of a database made in MS/Access with as subject cacti and succulents and, there will be an increasing amount of associated files and pictures that will accompany this database. Currently we have a small body of users all over the world. The current distribution method is mail

In the database we will log who contributed pictures and whether these pictures are available for download.

The requirements are:
* it has to be low cost.
* the files must be worldwide available
* it has to be free of stuff that people may object to

Nice to have would be
* one or more central locations that can synchronise
* ability to contact/chat with people interested in the distribution
* log of who added pictures to be available for download.

Personally I think ads may be ok, spyware is a definite nono.

The potential amount of data is huge: there are some 13.000 species in the database at this time. In an ideal world we want to achieve some 7 pictures per plant

Thanks, for any suggestions
Gerard
