  We consider a stochastic model, describing the growth of two competing
infections on $\mathbb{R}^d$. The growth takes place by way of spherical
outbursts in the infected region, an outburst in the type 1 (2) infected region
causing all previously uninfected points within a stochastic distance from the
outburst location to be type 1 (2) infected. The main result is that, if the
infection types have the same intensity, then there is a strictly positive
probability that both infection types grow unboundedly.
