Looks good, but where's the compass?

I realize the analog compass solution is kludgy, but if you built a small tube/shaft containing the periscope mirror at the top and the ball compass at the bottom (with optionally an LED+button battery for illumination), it would be a one-piece, compact unit that would only need to be pressed against the user-facing camera to be used, and could be pocketed when unused.

It seems that the other solutions are:
1. Pre-built compass module + bluetooth module (e.g. from SparkFun) + battery.
2. Custom PCB + surface mount compass chip + bluetooth chip + battery.
3. Ready-made serial compass module OS-5000.

Based on the hardware modules I found by searching the web, option 1 would probably be bulkier than the analog compass solution. Option 2 could potentially be made small, but the battery will still make it bulky, and it requires equipment to etch a board and do surface-mount soldering. Option 3 would be very small, but requires USB host and costs almost $300, which probaby most people will agree is too pricey.

I guess we can still hope for Option 4, that the shipping delay is due to Nokia adding a built-in compass...

I'm not saying the analog solution is optimal, just that for someone like me without PCB/SMT tools or skills, it seems like a workable, low-cost, low-risk kludge. The small analog compass strap is also at least useful by itself.
