Jason used the tecnology to get his vehicals in and out of cheyanne mountain, though it was called a space-conveyor.
PPG's are small which implies that the stretched space technology is very small as well. The Karrines were much more advanced than the rest of the imperium in there technologies. More specifically they had a greater lock on space and dimension technology, as witness their hyperspace technological advances.
Therefore I would have expected them to be equally advanced in their space stretching technology (I suspect that this is the technology that Myleena is using to miniturize the singularity power plants along with moleculartronic circuitry).
So why doesn't Jason or the Karrines carry portable stretched space 'holes'. If they can carry a device the size of a PPG I would expect them to be able to carry a 'hole' big enough to carry say - Jasons armour (complete with weapons).
I should think a device attatched to a belt about the size of a tobacco pouch should be able to generate a 'hole' big enough to store virtually an entire wardrobe at the very least big enough for an armour pocket.
