Colour Management for Client Multi-Purpose

[beckym]

I'm fairly new to freelance photography, doing some work on commission for small organisations for their PR multi-purposes (often for a printed publication plus their website). I deal directly with them and supply them with a CD of files - if they want to print, they then outsource printing to a designer / print house (with whom I have no contact).
If I work with and supply Adobe RGB, this will be best for their print house to convert to CMYK - but I have had comments from my client (viewing images in un-colour managed setting) that images look dull/flat. But if I convert and supply in sRGB, though its better for their viewing and their website, will be less than ideal when they ask the printer to put one of the photos on the cover of their annual report.
As a workflow solution, do professionals in this situation tend to supply two versions of all files, or go for one or the other??

Many thanks for tips!

Adobe RGB will be fine for CMYK output IF supplied to outsiders who understand and use color management correctly. If not, it could be problematic although that's more due to clueless users who will not see the images (or convert) correctly due to their misunderstanding of working spaces.

If you're sending someone who you suspect doesn't understand color management, ColorMatch RGB for CMYK work is ideal (although a dumb user can still screw that up of course).
