Need help on delegation to subdomain/external servers

i'm using BIND9 on an Ubuntu-8.10-server.
I'd like to configure the following:
For a given name (eg. vega.lab.ts), I'd like to forward the request to
two external DNS servers, *simultaneously*, and respond with the first
response that i get.
Is this possible?
I didn't see how to do it directly, so i tried using a subdomain, (eg.
x.vega.lab.ts) and specifiying the two DNS for this subdomain:
Extract from the lab.ts zone file:
x.lab.ts. IN NS vega-a.x.lab.ts.
x.lab.ts. IN NS vega-b.x.lab.ts.
vega-a.x.lab.ts. IN A 172.25.32.252
vega-b.x.lab.ts. IN A 192.168.2.3
But this doesnt seem to work:
named-checkzone lab.ts /etc/bind/db.lab.ts says:
zone lab.ts/IN: x.lab.ts/NS 'vega-a.x.lab.ts' (out of zone) has no
addresses records (A or AAAA) zone lab.ts/IN: x.lab.ts/NS
'vega-b.x.lab.ts' (out of zone) has no addresses records (A or AAAA)
zone lab.ts/IN: loaded serial 2 OK
How can i do it?
