[atlas] Spoofing the source IP address from a probe?

Hi,

I think some hosts would like theirs probes to be used for "source IP 
spoofing" check, and only such probes could be used for this particular 
type of check.
If RIPE Atlas team implement such features then probably many hosts will 
"enable" "Source IP spoofing check ability" on theirs probes and that 
can serve for community at the end.
Of course overall mechanism should be in a way not make anyone to 
suspect that probe can do spoofing by default or probe can do any 
harmful thing.

I have personally run Robert Beverley's probes regularly for many years and I am proud to say that both my broadband providers have never allowed source address spoofing. This involves a conscious decision on my part taking into account local network etiquette, my relation to my providers and the local legal situation. It is very very different from the RIPE community deciding to use RIPE Atlas to do this from my network.
