InfoPath Dev

I'm our SharePoint admin but got a request to look into this.

A business unit has a MOSS team site with a document library (Training).

They would like to have an Infopath form (browser only) that gives them a choice to either

1) Send an internal email (within the company) with URL links to one or more of the documents in Training.

   OR 

2) Send an email externally with one or more of the documents from Training attached to the email.

So, I envision a form that pulls in the the list of all the files in the Training library into a table, and has a checkbox next to each (a check all here would be nice). The user could then either have option buttons or two Submit buttons to either send as attachments or links.

Can this be accomplished using Infopath Forms Services/MOSS 07?

Thanks for the reply Patrick. Is Infopath 2010 out of NDA status enough that you could answer whether attachments in IPFS is coming? If not, we will probably be spending dollars on developing a solution ourselves.

 Edit: also, how would this picture change if our email senders had the Infopath 2007 client? Would #2 then be do-able?
