I'm not sure if it meets all of your criteria, but look at www.bugcentral.com

>Hi,
>
>Any recommendations/ideas/warnings regarding Bug/Defect tracking software? I'm ideally looking for something that does the following:
>
>1 - Web based or at least strong web access
>2 - strong work flow/approval assignment capability
>3 - integration with MS Project (or it's own project management built in)
>4 - customizable
>5 - works with SQL Server/IIS
>
>We're looking at tTrack from TeamShare pretty heavily. It seems to be very good and fit the bill on all 5 items, but it is very expensive (at least for us - 15K-20K)
>
>Any comments on tTrack or any products in this category?

>Thanks!
