You could use a func as your iterator and keep the state that you are changing in that delegate to be evaluated each iteration.

public static IEnumerable FunkyIEnumerable(this Func> nextOrNot)
    {
        while(true)
        {
           var result = nextOrNot();

            if(result.Item1)
                yield return result.Item2;

            else
                break;

        }

        yield break;

    }

    Func> nextNumber = () => 
            Tuple.Create(SomeRemoteService.CanIContinueToSendNumbers(), 1);

    foreach(var justGonnaBeOne in nextNumber.FunkyIEnumerable())
            Console.Writeline(justGonnaBeOne.ToString());
