@beer$$money: Excellent post. It looks like we are realistically about 1-2 quarters away from seeing an explosion in top line growth from O&G revenue - alone.
With the recent health care developments and their potential with correlating generator leasing, many signs are strongly pointing to green days coming soon.
More of an X-factor (my term for a strong yet difficult to measure possibility) to assist with this upward trajectory is other hospital groups /hospitals seeing the success of on site solution generation from these previous sales. Think of healthcare market success and their supporting case studies.
Within mature industries, a quality/value product can/will eventually reach "branded status" and begins to sell itself with less marketing effort (adding to the bottom line).
Of course, I have only spoken on O&G and healthcare. There are other industries such as agriculture and retail that can and should dovetail off the above success.
