Genuinely interesting, my employer's primary business is acquiring companies, typically we do not subsume them and expect them to adopt our systems/products, we just support their existing and offer alternatives that will ultimately be cheaper because we have more clout when it comes to contract/licensing negotiation. The downside is the enormous list of products the support team must familiarise themselves with.
