Moonless Wspace Systems

Here's a small suggestion for CCP to spice up wspace just a little.  Put in some wspace systems -- not too many, perhaps 1 in 20 -- which have no moons.  

Such systems would be interesting places because they could have no POSes anchored.  As such, they could be occupied only tenuously, via anchored containers in a safespot.  Lacking permanent occupation, they would tend to build up lots of signature sites and anomalies.  They'd be nice finds for doing PVE in.  However for that same reason, they'd also be good places for PVP.
