[Snort-sigs] rules licensing

I am wondering about what the licensing policy is for the snort rules being distributed. The rules files themselves do not have the GPL notice that can be found at the head of snort source files, only a copyright notice. But they are available for everyone to download, and are a result of collaborative work from the snort community. So what is the policy about copying/distributing snort rule files (the ones downloaded from the snort site, or modified versions thereof)?

Examples: can whoever modify some snort rules and put them up on a webserver for everyone to use?
if free-ids.org develops a new opensource ids software that can read snort syntax, can he ship snort rule files with it? does this force him to go GPL for his entire project (rather than use some other free software license)?
if make-money-with-ids.com sells a NIDS developed from scratch but compatible with snort syntax, can he ship those rule files with it? can their customers download the rule files themselves?
