I am looking at a possibility to change my ASP.NET 2.0 app to Mono framework. I have used the mono analyzer tool and it does detect some p/invoke and interop dependencies.

For ex. 1) We use excel interops and on linux we are looking to use staroffice/Openoffice instead. Is there an easy way of substituting excel with staroffice? (I know it sounds bizarre, but just don't want to miss out in case anyone has done it already.)

2) LDAP auth: What could be the best alternative in Ubuntu (or an other flavour of Linux) ?

3) Is there an ajax framework for mono? Preferably with similar controls as Atlas??

I hope I am not too ambitious here..

thanks.
