XP remote Desktop Admin

we are testing the web remote desktop admin in advance of rolling the new XP Pro machines out in a months time or so. I have some security fears on this and wont let it be running unless I am as certain as I can possibly be that this can not be exploited easily. Does anyone have any info on this feature Ive looked around microsoft and all I can find is the hype, no specifics on security issues for the Remote Web Access in XP. Thanks for any assistance.
