Leveraging RAS without loggin in to lbi

This might be a little off topic, but let's see what you all think. We've got a data collection website that really has nothing to do with Lawson. Since we already have staff with SQL, Crystal Reports and LBI skills, I'd like to figure out how to leverage them and LBI or just the RAS service to provide reports to users of the non-lawson system without them having to log in to LBI. They don't have user names for LBI and the business owners of this other system are not very keen on making users log in to a second system to get a report. The easiest solution would be to set up a 'report' user id and pass those credentials along with the url from the non-lawson system. Alternatively, I could add a page to the non-lawson system that would give the user a place to enter parameters. This would be bypassing LBI altogether and going directly to RAS. I'm not sure that's possible. Has anybody tried either of these before?
thanks
