About the database : is it really not possible by using GDBM, to check duplicate maps ? You're speaking about 5% of empty duplicate maps... with Google I think, but using OpenStreetMap it's more about 90-95% of "empty" maps in France !
If 90% of maps are 106 bytes, and the other 10% of maps are an average of 15k, removing the duplicates (even with no overhead) saves you just 5.85% of your disk space. And, in reality, tracking duplicates requires about 16 bytes per duplicate, so it'd be difficult to obtain a savings that is worthwhile.

If you are looking for a tester, I am willing. Of course I would only publish my results to you directly. Apart from that, great work!!! So go man go!!!
Anyone else interested? I'll contact you through ITT PM, if I decide to host a beta.

Count me as a tester if need be ...
Do you think we can have the two versions at the same time on the tablet ?

I'm very interested for a beta test.
For the empty tiles, you must be right : they are insignificant since we use a database ; otherwise it's consuming some more space for an complete cluster for each file/tile : 8k ?

I am also interested in testing.
I have no plans to go any where for next 30-40 days except roaming in my home town (which I know very well), so even this beta version not working well, it is not going to harm me in any way.
EDIT: by the way I am using 770n with OS2007.

I too may act as a beta tester. I am sometimes on the road for long trips (300-500 km) twice or more a month, while I travel anyway a lot during my "regular" life.
Today I am 500 km far from home and will return here next monday.
No problem if I'll lose tracks or whatever since I also own a Sony TH55 loaded with Tomtom so I can find anyway my way home

Please count me in for beta testing. I'm interested in performance on the 770 with all the changes you're making.
