Scheduling Application Design

Hi,From a high level the scenario is as follows1. Users from each department submit individual documents containing the schedule of each department.2. The system should collect each individual document and produce a summarized document containing the schedules of all the departments.�  The initial summarization process should be automated but the main user can change this manually.�  3. Once the summarized document is created the system should distribute this (through email or some other means) to each individual department.4. For both step 1 and step 2 the interface should be web based.My questions are as follows1.�  What kind of tools/technologies can I use for this scheduling process?2.�  Can SharePoint 2007 be used for this in some manner?3.�  Are there any tools out there that I can use to get this done or already does this?ThanksArjuna. ...
