thats very easy... and its obviously doable... since as we speak bodis allows redirecting there as one of their external market options.. and they always have.
however their auction page if used as a sale lander redirect is very bad... confusing for most buyers... then again, most sales for most people hapen on gd so maybe its not so bad...
this is one of my gd listed names.... just do this... put your name at the end:
https://auctions.godaddy.com/trpItemListing.aspx?domain=vrsign.com
or even easier.. join bodis... add your names.. and with one click switch betwen various market landers.. dan gd sedo... etc... with or without bodis parked page...
obviously, iu can do this for any names.. not just gd regged names....
p.s. what do you mean by "default page" im curious? like when you search for name to register?
hope this helps.
