Plus, if I create a feature whenever I received a lon/lat, will this way slow
down the system when many many TCP/IP clients sending data to it?

Hi all,
I want to display a serie of points, which are drew based on lon/lat received
from a TCP/IP client (Yes, a simple GPS tracker)
These points are not going to be built as features.
Although I can get the screen position based on the lon/lat, I find when I have
PAN or ZOOM action, those points which have been drawn will disappear while new
points are still showing successfully.
To keep those points showing, my idea is storing the lon/lat of all received
points, when repainting, the screen position of all those stored points will be
recomputed and redrawed.
But is this the best way to do this?
If someone can provide me example code, I will appreciate much.
Thx.
