Anyone exercised this option within their application? Just wondering about using it as a software protection option - might have to configure some sorta database to allow folk to submit a request for a license key, just one option I'm considering.

Something like this? http://security.stackexchange.com/questions/1118/can-i-block-based-on-mac-address

Consensus seems to be that it's a bad idea and not really worth pursuing. It sounds like you need to grossly violate user privacy for even mediocre success and a savvy end user will still work around it with ease.

Thanks for the feedback Yasha, that is along the lines I was hoping for

I read that. It's interesting.

" If you could determine the MAC, that would be a pretty big privacy violation. Since your MAC address arguably identifies you uniquely on the globe,... "

" Blocking an attacker by MAC would be the same as blocking him/her by cookie because it is controlled by the client. "

I barely understand networking stuff, except for what I read here.

I coded a customized DLL for Blitz3D to return your MAC addresses.

This successfully returned the physical addresses of both the
Wireless LAN adapter and Ethernet adapter on my machine; Your results will be similar.

You can download my zipped code, [ BB + DLL + decls ] from this link
( Remember to put the decls file in the "UserLibs" directory. )

Aha! Did you really think I'd show you my MAC address.

The Blitz3D program is very simple, as follows:

;; The "getMAC()" function returns a different MAC address each time it's called,
;; and returns an empty string ("") when it's out of data.

Print
Print" Your MAC physical addresses are :: "
Print

mac$ = ""

For z=1 To 10
mac = getMAC()
If Len(mac)=0 Then Exit

Print " "+mac
Next

Print:Print:Print

Print" Touch a key to end. "
WaitKey():End

thank's for sharing

i used blitz.sys to get the HardDrive ID and used that as key.

http://www.melog.ch/dl/blitzsys_v105.zip

this sample code grabs the hard drive id on a text file:

Include "incluir\blitzsys.bb"

DebugLog "volume serial: "+Hex(DLLGetVolumeInfo("C:\",VOL_GETVOLUMESERIAL))

out = WriteFile("id.dat")
WriteLine out, "volume serial: "+Hex(DLLGetVolumeInfo("C:\",VOL_GETVOLUMESERIAL))
CloseFile out

Print "press a key..."
WaitKey

End
