We work with a lot of companies that have deployed Microsoft OCS and then discover they need a solution for viewing past IM conversations. In some cases the requirement stems from regulatory compliance issues; in others, it is legal discovery or internal usage policy auditing and enforcement.
Whatever the reason, some companies decide to address their needs with an internal development project.
We've compiled our experience (and theirs) into a 'build or buy' white paper. If you're thinking about building your own OCS archive viewer, you need to read this document. You can download it for free from our white paper library.
