as i has already been said having to maintain the code on several hosts will make it more trouble then it is worth. What you have to think is you would need to make sure that it uploads properly over several hosts, it would more then likely cause confusion to some over if one copy is legit and the others aren't which in turn could cause a bad name for the project before you even start.
End of the day there are much more, better ways to spread the word of your project, social networking sites, specific related forums are two main ones for you to consider, either way you would be better off spending your time posting to several sites then you would uploading and maintaining code on several sites.
