THe problem is I dont think it is possible to jump like that. All of the nodes are tunnels that lead to other ends. You can only come out of the node at its opposite end. Lets say you were in Polaris, where both Regulus and Sirius jump nodes meet. If you jumped into one end of the Sirius jump node, you would come out the other end of the Sirius node, not the same end within the Polaris system of Regulus node. It isnt like you enter any node and can go to any other node: only the end of the node you just jumped into.
ALSO, this nano jumping bit that Bob mentioned... I dont think it would work out either. I'll quote myself to explain why from another thread:
"Think about in FS2, whenever command says something like "The GVD Psamtik has made the jump to where you are! It should arrive shortly!" Well, wait 10 seconds and boom, there it is.
Given the speed of travel while in subspace, 10 seconds must mean that the Psamtik is, while still in the same system, a great deal away. So now your talking about jumping 4 klicks? That takes what, .0000001 nanoseconds? Now I understand that not every bit of the FS Universe goes along with reality, but I highly doubt there is an engine out there that can power up and then completely power down within .0000001 nanoseconds in order to make said 4 klick jump.
It's just not possible to make an engine that can power up and then shut off that quickly. NOW, the Psamtik could take an alternate route. Say, jump 3000 klicks one direction, out of the field of engagment, then set the computer or whatever to turn directly around and jump 3004 klicks, just past the field of engagment and into the jump node."
So making those "nano-jumps" possible would kinda screw with the whole FS universe. Sure, it occured in the Inferno campaign, but Inferno isnt official [V] material, either.
