Hello,

There are a number of different ways you could do this, including:

1. Creating infopath-compatible Xml manually and adding to a form library
via (for example) the Sharepoint .NET API;
2. Creating infopath-compatible Xml manually and adding to a form library
via (for example) the Sharepoint web services;
3. Automatically submitting an infopath form to a form library;
4. Automatically submitting an infopath form to an email address, and have
that email address submit to a form library
5. Create a workflow component that, when triggered, creates
infopath-compatible Xml and adds it to the form library

It really depends on what you know best and what you want to achieve.  It's
a case of "choose what works for you" :)

Gavin.
