Type cast it to an array is one way:
Type
TBigArray = array[0..10000] of byte;
RecSize := SizeOf(Rec);
HandleItSomeHow(@Rec,RecSize);
procedure HandleItSomeHow(Var Rec; Size : Longint);
Var
S : String; //make sure its a LONG string
begin
SetLength(S,Size);
Move(rec,@s[1],size);
StreamStringOverNetwork(s);
end;
Or something like that. Dunno how it would handle nulls, but it
should.....
