Test-bed identification

Hi!
We need to run test-cases & test-sets on different test-beds (HW setups). 

Are there any 'elegant' way to add  the test-bed identification to the test execution which will be inherited by the test-run? So later we can check which test-run was made on a given test-bed. Recently we created 'fake' releases, where the last segment of the version # points to the test-bed. The release can be selected as the test-execution starts.  (In case of test sets use the 'schedule' field.) Any better idea?

Thanks!
