Today here in Sweden, discussing the various option for indexing content sources I mentioned there are a number of places the SPS index engine can visit. I mentioned that out of the box, you cannot immediately start indexing Lotus Notes database. Actually, I was half wrong since SPS is capable of doing this if you make sure you get everything installed and configured properly on your SharePoint index server.
Edhild has a good posting for everybody who wants to try it out. I do like the comment on his post ("is lotus notes the ugliest (aesthetically) piece of software or what... ;-)" - not a big fan of Notes myself I totally agree. Let's all move to SharePoint :-).
