And here we go:

Everything we need is right here, but there are some limitations, most of which are defined by your account level.
There is a maximum of 6 standard refreshes per hour.
The general policys we need to be concerned with are as follows:
User's Guide.
http://developer.yahoo.com/mail/docs/user_guide/
The following material needs to be thoroughly gone over:
Terms of Service:
http://info.yahoo.com/legal/us/yahoo/utos/utos-173.html
Terms of Use:
http://info.yahoo.com/legal/us/yahoo/api/api-2140.html
Yahoo! Developer Network Guidelines:
http://info.yahoo.com/guidelines/us/yahoo/ydn/ydn-3955.html
None of these are terribly restrictive!
Now there is a project registration process, and I will step up and place from my account, but only if there is serious interest.
A programmer may or may not be necessary to assist in this as I am no programmer, so please review the user's guide link closely.
There is also one other open source solution, and it is a bit outside my current understanding, as I have not had the time to fully research this solution.
------------------------------------------------------------------------------------------------
YPOPs! is a free open source software that provides POP3 and SMTP access to Yahoo! Mail. You can use your favourite email client, be it Outlook, Thunderbird, or whatever else you like and connect to Yahoo! Mail seamlessly.http://ypopsemail.com/
YPOPs in their own words does the following:
this application is more like a gateway. It provides a POP3 server interface at oÂne end to talk to email clients and an HTTP client (browser) interface at the other which allows it to talk to Yahoo! The same concept holds good for SMTP as well.
Since this application is open source the code is freely available. I have been in contact with these folks and they would be unopposed to our own development based on this work.
I am unsure if this a viable solution, but everything is worth looking into.
If you have any questions let me know.
