Ways to mass post to WordPress - not using AMR or AD

Hey guys,

what automated way can you think of to post a certain number of articles - drip feed - each to a specific wordpress blog?

We do spin the articles but neither ArticleMarketingRobot nor ArticleDemon support some of the formats we need AND both cannot make sure that each article is at least 90% unique. This is what we need to make sure, tho.

So we need some other tool that selects a text file from a pool of textfiles and posts it to one of the specified wp blogs. Then afert x minutes it takes the next and posts it to a different blog... If possible the "tool" should be able to create a report but that is optional.

I have thought about doing it via email using mass mail function of MS Word + Outlook. But here we cannot drip feed.

Autoblogging? CSV Importing? All made for different purposes and would not allow this and I cant think of a way to do it with these plugins.

Multisite is also not a solution because the sites are split on various servers. And they do not use multisite.

Is there any script out there that does exactly this?

Thanks for your help - we appreciate any clue and will post whenever we find a solution ourselves
