external integration features

[samskeyti]

i would like to know if SMF (or some modifications) has these features:

- possibility to post a new topic by an external PHP script (using some API) choosing the forum in which the topic goes and the user who posts it

- the same as above but posting a reply to a specific thread

- the same as above but posting a private message to an user

- getting the rss feed from a particular forum only or from a particular topic only

- getting the rss feed of private messaging by authenticating (on the fly) the user

- auto registration of users by an external PHP script (using some API) and if you register this way you avoid the confirmation e-mail


i need these features for doing this:
- users register at my site and automatically register in the forum
- users login in my site and automatically login in the forum
- users do some actions in my site and automatically a topic is created in the forum
- users read theirs private messages directly from my site (by an rss feed)
- users read topics directly in my site (by an rss feed) maybe also from private forums if they are special users
- users send private messages to others directly from a form in my site
- users post topics in the forum directly from a form in my site

can you tell me if there are something that i cannot do?

thanks
